Application filed October 20, 1926. Serial 110. 142,868. I

This invention relatesto looms for weav- .ing tuft pile fabrics, such, for instance as Axminster or Moquette carpets or rugs and the like, wherein different yarns are taken from a source of supply and passed about threads in the body fabric to form the tread surface thereof.

In tuft pile fabric loomsofthis general type, the tuft formingyarn is wound upon spools mounted in tube frames, which are connected to a carrier for moving the tube frames into the tuft yarn presentin position. In some instances the tube frames themselves are taken from the carrier by appropriate means to transfer the row of tufts to the weaving point, and in other cases it has been proposed to withdraw thetuft yarn from the tube frames by grippers, out elf appropriate lengths of the .tuft'yarn and their cause the grippers to deliver the lengths of tuft yarn to the weaving point or fell of the cloth; Looms of the former type are necessarily slow in operation and consequent production of fabric, and in the latter type, wherein the tuft yarn is taken in lengths from the presenting mechanism and delivered to the weaving. point or fell of the,

cloth, the character of mechanism employed has necessitated comparative; slow movement of parts in orderjthat their paths of movement may not conflict.

The presentrinvention relates more particularly to the gripper type of tuft pile fabric looms and has for its object to provide a loom of this character which may be run at high speed with consequent increased production and wherein the'parts' are so correlated and actuated that perfect, tuft pile fabric may he produced. 7

An important feature of the invention contributing to these ends consists in a construction whereby the dents of the reed carricd by the lay are moved "in paths. of nonintersection with the weft insertin' means whereby the weft may be inserte in .the shed before the dents have been moved rear- ,wardly back of the path of movement of the weft inserting means; Another equally important feature of the present invention consists" in mounting the grippers for movement in a backwardl and downwardly extending path through t e warpthreads to deliver the threads, and also the interference that may occur in the movement of parts as the grippers deliver the tuftjyarn to the -weaving point, and another important feature of the invention therefore consists in providing means for insuring a proper guidance oilthe grippers in their movements to properly direct the ends of the grippers and the tuft yarns held thereby between their associated warp threads and the non-interference with the reed dents. Inthis connection, also, the present invention contemplates guiding means for the reed dents so associated with the guiding means for the grippers that both the reed dents and grippers are maintained in proper lateral relation during their respective movements.

Another important feature of the present invention consists in mounting the rippers the trailing end of the tuft ya'rn to be raised into'its proper relation with the held end of the tuft yarn. w The guiding means for the grippers and reed dents is of novel construction and serves to laterally position these parts as well as the: warp threads with which they are associated, so that perfect cloth shall be woven.

Heretofore it has been the common racticc to form the breast comb from a single bar inwhich are cut a number of breast'teeth. an operation both expensive and inaccurate in its results. and in accordance with another feature of the present invention the breast previously comb is formed of separate breast teeth;

whereby facility of manufacture is secured,

and means are provided for holdin such separate teeth in proper spaced-relatlon on the breast beam.

It is desirable at times that one or more of the reed dents carried by the lay be removed, and the present invention provides means for readily accom lishing' this end without disturbing-the aifiacentdents.

When the grippers have withdrawn the len hs of'tuft yarn from the tube frames, a sh ing bar provided with teeth along its edge is moved relative to the tuft yarn to engage them between the teeth of the bar,,and a cutter has usually been mounted for movement transversely of the loom to shear or cut the tuft yarn held in the teeth ofthe bar.-

Heretofore the cutter has occupied its cuttin position relative to the teeth of the bar, wit the result that it prevents the adjacent tuft yarn from engaging the teeth of the bar,

, so that some of such tuft yarn may not be cut. In accordance with the present invention, however, the cutter or shearing knife is normally held in an inoperative position relative to the toothed bar to permit the tuft yarn to enter the teeth of the bar and upon movement of the, cutter .in. its tuft-cutting operation, it is first moved into operative po-. sition relative to the teeth of the bar, with the result that all of the tuft yarn having been engaged between the teeth of the bar'are severed during the cutting stroke of the cutter.

The invention, new. features thereof, and

novel combination of parts whereby increased production and high speedare attained, will est be made clear from the following .de-

The loom frame 1 may be of usual or convenient construction for supporting the operating parts and, as shown in the present instance of the invention, theloom frame is provided with-the risers 2 which afford sup port for a carrier shaft 3 about which passes the carrier or chain 4 on which the tube frames are mounted. Each'of the tube frames 5has associated therewith one or more spools 6 on which may be'wound the tuft yarn of appropriate color suitable for the pattern to be produced, as usual. The carrier or chain 4 may be given proper movements for presenting a tube frame in position for the tuft yarn extendin therethrough-to be taken by the grippers, but since the means for actuating the carrier form no part of the present invention and its actuating means being wellmoaere warp threads in the formation of the shed may be of usual character and as herein indicated comprises the frames 8 and heddles or the likehaving eyes 9 through which the warp threads a pass. The shedding mechathem may be of any usual type and be actuated from any convenient source of power,

but siiice the details'of such mechanism form no part of the present invention and are now well understood, they are not herein shown.

lihe weft inserting means indicated in Fig. 2 consists of a needle 10, as is common'in this type of loom, and means are provided, though not here shown, because the details thereoi form no part of the present. invention, for

moving the weftinserting-ineans or needle- 10 through the shed formed by the shedding mechanism. As usual, the weft inserting mechanism or needle 10 inserts a double wett Z) in the shed, but the particular means and number of weft inserted may be varied.

Mounted at the front of the loom is the breast beam 11 over'which the tuft pile fabric 0 passes on its way to the take-up or toothed roll 12.

' The lay 13, Fig. 1, carries the dents 14: which extend upwardly therefrom in separated relation to beat up successive wefts, and is mounted for rocking movement on the shaft 15. Extending downwardly from the lay 13 is the arm'16 connected to -a rod 17 having a roll 18 which travels in the cam path 19 of the cam 20 mounted for rotative movement on the shaft 21, the construction being such that as the cam rotates itwill cause the lay 13 to rock on its shaft mounting 15 30 mounted for rotative movement0n the shaft 21,-the construction being such that the dents 14 are given a path of movement as they retire from the fell of the cloth to carry the ends of the dents out of intersecting relation with the weft inserting means or needle 10. This characteristic movement of the dents is indicated inFigs. 8, 9 and 10 by the dotted lines d, wherein it will appear that the dents move from heat up position in a downward and backward direction to carry the tops of the dentsbelow the weft inserting means, as indicated in Fig. 9, so that before the dents have reached a position backward of the path ofmovement of the weft insert-- 'ing means, the latter may insert the weftwithout interference by the dents. The dents being in their backward position, as indicated by fulllines in Fig. 9, and the weft having been laid in the shed,-the dents are raised by the train of mechanism hereinbefore described, into the dotted line position indicated in Fig. 10, so that the front edge portions of the dents are back of the weft and on frontward movement of the dents the weft is beaten into the fellofthe'cloth.

This enables the loom to be run athigh speed 'beause the weft inserting means does not have to delay its weft inserting movement until the dents haveretreated. backward into a position beyond the pathof movement of the weft inserting means, or, in other word's,the weft insertin means may be actuated to insert the weft into the shed as thedents move from their beat-up to their rear ward position.

In accordance with the present invention the grippers, of which there-are a series,.are moved from their tuftyarn taking'position in a backward and downward directionto carry the ends of the grippers and the tuft yarn held thereby below thewarp' threads and to lay the tuft yarn over the face of the comb, with the trailing end extending downwardly, as the gripped end of the tuft yarn is raised by-the grippers above. the warp threads." The tuft yarn being in the posh .tion stated and the dentsmovmg forwardly to the beat-up, the grippers release the held end of the tuft yarn, while the weft as it is beaten up, causes the downwardly extending free end of the tuft yarn to be moved upwardly over the face of the comb into the full beatqip positionat-the fell of the cloth.

In order to facilitate speed ofoperation of the loom and consequent increased nroduction, the grippers are returned upwardly through a backwardly and upwardly extending path difi'erent from the path of movement followed by the grippers as they carry the tuft yarn to the weaving point, and such return path of the rippers is non-intersect ing with the path 0 movement of the weft inserting means, with the result that'thc weft insert ng 'means or needle 10- may insert the weft intothe shed without interference by either the dents or the grippers in their inactive or return movements.

In tuft pile fabric llooms of the gripper type the grippers are liable to become displaced as they-move to carry the tufit yarn to the weaving point, and such displacement is liable to cause the grippers to pass between thf'eads other than those betweenwhich they are intended to pass, and also, in some cases, to contact with the dents-. The present invention, therefore, contemplates means for guiding the grippers during their movements to maintain them in proper relation with the warp thieadsthl'ough which they tillare to pass, and also with'respect to the dents carried by the lay, and'inasmuch as the grip pers and dents approach the weaving point or fell of the cloth in slightly different latpreferably constructed to guide not only the grippers in their movements but also the dents.

Having reference more particularly to Figs. 2, 19 and 20, the means for guiding the grippers and dents consists of guiding mem-' bers, of which there is a series, between which the grippers and the dents move. In theparticular construction shown, the guiding means consists of the plates 31 secured to the loom frame and extending frontwardly preferably to or beyond the face of tliebreast comb. Since the dents are guidedv in a path laterally separated from the path of movem'ent'of the grippers, the guiding plates 31 are preferably formed of bent sheet metalhaving a lower portion 32 wherein the metal is doubledupon itself, as indicated in Fig. 19, thereby producing a guide 33 in which the dents 14 movetowards and from the fell of the 'cloth, and between the several plates 31 a guideway 34 isprovided for guiding the grippers in their movements towards and the dents and the grippers, are accurately maintained. in their desired paths of move-;

mentwi'thout interference and for directing the grippers between the proper cooperating warp threads. In order that the-warp threads (1 may also be guided in a path laterally of the grippers, each of the guide plates 31 is-provided with'an opening 35 through which the war -threads, usually three, pass on'their way rom the usualtwarp' beam or warp supply to theweaving point or fell of the cloth. The effect of this is indicated in Fig.19, wherein it will be noted that the warp threads a'are passed laterally through the openings 35' and consequently lie closely to the surface of the guide-plates 31, thus maintaining the warp threads in proper relation with the grippers which are to pass between them. Fromthe construction described, as one form of this feature of the invention, it will be apparent that the warp threads, the gr ppers and the dents are guided in their respective paths in correlated relation with each other and separated from each other laterally, so that all danger of interference either by the dents or by the grippers with each other or the warpithreads isavoided.

The guide plates 31 may be secured to the loom frame in appropriate manner, but as herein shown, they are mounted upon crossbeams'36 and 37 extending transversely of the loom frame, and are held in spaced relation by the spacers or racks 38, which may he formed with spacing teeth 39 between which the plates are seated. The frontwardly extending end portions of the guideplates 31 are secured in place by locks which maintain the guideplates seated in the spacers 38. The uideplate locks may be variously contrived, but in the present instance of the invention from the weaving point, theeflect being that guideplates, said locks may be entered transversely through said openings and then turned downwardly to embrace wlthin the slots 42 the several guideplates which are thus held in spaced relation and locked in their seats or spacers 38. From the construction described it will appear that the'guideplates are held in proper spaced relation and locked in position, and yet are capable of being removed by manipulation of the lock when it becomes necessary for repairs or otheripurposes,

, Inasmuch as t he guideplates 31 guide not only the grippers but also the dents, in the preferred form of the invention, the guideplates 31 are each provided with an opening 43 which openings are alined transversely of the loom when the guideplates are in position, for the passage of'the weft inserting means or needle 10, as indicated in Fig. 2.

1 It is believed that the present invention affords the first instance in the art ofgrippers for taking lengths of tuft yarn from the tuft yarn presentin mechanism and guiding the movement of the grippers to the weaving point, and it'is also believed that applicant is the firstQto provide guiding means for. the grippers and dents to maintain these parts in thelr respective paths of operation, so that while the above form of guiding means affords a ,good practical instance thereof, it is to be understood that the guiding means may be variously contrived to efiect the results-hereinbefore noted.

The grippers for taking lengths oftuft yarn'from the tuft yarn'prese'nting mechanism and deliverin them to the weaving point are mounted for movement in a back wardly and downwardly extending path, as

hereinbe fore described, and comprise the gripper shaft 44 (Figs. 2 3, 4,5, 6 and 7) which has afiixed thereto the gripper jaws 45, In the present instance of the invention, the gripper shaft 44 is providedv with a series of slots 46 into which the heel portions 47 Y of the grippers 45 extend,- and the grippers are held therein by suitable means, such, for instance, as the headed bolts 48, the head portions of which enter recesses 49 formed. in' the heel portions of the griiippers, as indicated in Figs. 2-, 3 and 7, the e ect being that the gripper jaws 45 are substantially rigid with the gripper shaft 44 and held in spaced relation;

The gripper shaft 44 is mounted eccentrically in rotative hearings or bushings 5Q sup- 12 ported in-bearing'blocks 51, one at each side of the loom, and each rotative hearing or bushing is provided with a gear 52 which is actuated by a toothed rack 53 for the purpose of turning the rotative hearing or bushr may be enclosed in a casing 55, as indicated.

The gear 54 is actuated by a toothed rack 56 to cause rotative-movement of the gripper shaft to carry the grippers from their tuft arn receiving position to the tuft. yarn de-- ivering back.

The means for'actuat-ing the gripper shaft and rotativ'e bearing or bushing may be varied, but in the present instanceof the invention a shaft57extend's transversely of the loom "(Fig 1), and is mounted in' suitable. bearings and to the shaft 57 issecured a gear 58 which meshes with the gear '59 secured to the shaft21 below, it being-underposition' at the weaving point and stood that the shaft 21 is given rotative move-.

ment from a suitable source of power, to the effect that both the shaft 21 and the shaft 57 will be rotated. I.

- Secured to the shaft 57 isa ,cam 60 (Fig. 1) having a cam path 61 in which isreceived. a roller 62 connected with the toothed rack 56 for-operating thegripper shaft 44, as hereinbefore described, to move the grippers in their backwardly extending path towards and from the weaving point.

Also mounted on the shaft 57 is the cam .63 having the'cam path'64 which receives a roller 65 secured to the toothed rack bar 53,]

by which the rotative hearing or bushing 50 is given rotative movement for the purpose of bodily raising or lowering the grippers, as will hereafter more fully appear.

Keyed or secured to the gripper shaft 44 are the arms 66 in which is mounted for rotative movement the gripper closing shaft 67 (Fig. 7). The gripper closing-shaft 67 has a series of longitudinally extending teeth 68 '(Fig. 2) which are engaged by teeth 69 on the gripper closing jaws 70 'which'are or may be pivotally connected ,to the gripper jaws 45 at 71,..the construction being such that should the gripper closing shaft 67 be rotated clockwise; as in Figs. 2 and'7, -the gripper closing jaws will close upon the gripper jaws 45, a, condition which occurs when the grippers are in their upper tuft yarn gripping position.

Secured to the-gripper closing shaft 67 1s an arm 72 which extends laterall therefrom and is normally under the in uence of a spring 73 which, when the gripper closing shaft .67 is free to rotate, will actuate the gripper closing shaft to open the grlppers, and conversely, when the arm 72 is moved against the tension of the spring 73, it Wlll rotate the gripper closing shaft 67 to cause the grippers to close. Extending from the hub portion of the arm 72 is a shoulder 74 adapted to be engaged by a lock or catch o maintain the grippers C 0 sed when the arm 72 has been moved against the tension of its spring-73. In the present instance of the invention, the lock comprises an arm 75 pivotally mounted at 7 6 on a collar 77 secured to the gripper shaft 44, andsaid arm is provided with alocking shoulder 78 adapted to en age with the shoulder 74of the arm, 72 under the influence of a sprmg. 79 when the gripper closing arm 72 has been rotated to close the grippers. Thus, when the grippers have been closed, as will hereinafter appear, the lock maintains the grippers in closed gripping position until the lock is tripped.

The gripper closing and locktripping means'is best indicated in Fig. 1, and comprises a trip arm 80'pivotally mounted on the riser 2 at 81, having a backwardly extending 'POItlOIl which carries a roll or pin 82 adapted to ride upon the periphery of a cam 83 secured to the shaft 57. The roll 82 is normally maintained. in. engagement with the cam 83 by a spring, such, for instance, as the spring 84,;Fig. 1, one end of which is secured to a'fixed point as at 85' and the other end of which is connected tothe frontward+ ly extendingarm of the trip lever 80, asat 86. The frontwardly extending arm of the trip lever 80 is. provided with a tripping portion 87 which is adapted to engage at times with the arm 72 and with the lock lever 75.

Assuming the grippers in the position indicated in Fig. 3, wherein they are being moved in, their frontwardly and upwardly extending path towards the tuft yarn presenting mechanism, as indicated by the arrow, it will be noted that the lock is tripped and the gripping jaws are open ready to receive the tuft yarn from the presenting mechanism. From this point the gripper shaft and parts carried thereby, including the closing gripper jaws, are moved upwardly by rotation 'of the rotatable bearing or bushing 50, as herein- I before described, and the grippers assume an Fig. 4, and the shoulder 78 of the arm7 5 engages the projection 74 on the hub of the gripper closing arm 72 and effectively locks the grippers closed upon the tuft yarn. When the grippers have thus gripped tuft yarn, they will move downwardly to withdraw lengths of the tuft yarn from the tuft yarn presenting mechanism by rotation of the rotatablebearing or bushing 50 throu h the train' of mechanism described, and t e parts take the position indicated in Fig. 5.

v The gripper shaft 44 is now rotated to carry the I the grippers from the position indicated in Fig. 5, where the tuft yarn has been cut or severed from the presenting mechanism to deliver the tuft yarn to the weaving point. The path of movement of the grippers in carrying the .severed tuft yarn from the presentlng mechanism to the Weaving point is indicated by the dash and dot line a? in Fig. 1, wherein it will be noted that the ends of the grippers are passed backwardly and downwardly through the warp. From this point the grippers are moved frontwardly and upwardly and carry the gripped end of the tuft yarn above the warp threads; while the trailing end thereof rests upon the face of the breast comb, as indicated in Fig. 14. The weft having been laid in the shed by the weft inserting means, the dents 14 move frontwardly towards the fell of the cloth carrying the weft threads against the tuft yarn at the top of the comb, and upon further frontward movement of the dents 14 the grippers release the ends of the tuft yarn adjacent the fell ofthe cloth and the trailing end of the tuftv yarn is pushed frontwardly over the inclined face of the breast comb upwardly throu h the warp threads to form the completed tuft loop, as indicated in Fig. 6.

The gripper release is' effected by the lever 80, which, as indicated in Fig. 6, trips the lock 7 5 just prior to the full beat-up movement of the dents and then the grippers are returned to upper position for another supply of tuft arn.

As.hereinbefore noted, it is desirable that the weft presenting means shall be free to insert theweft without interference by the grippers on the return movement to their upward position for another supply of tuft yarn, and for this purpose the gripper shaft 14 is rotated in the opposite direction to carry the grippers in an upwardly and backwardly extending path in non-interference with the path of movement of the weft inserting means, as indicated by dot and dash line :1 Fig. 1, the effect being that as the grippers are moved upwardly and as the dents are moved rearwardly, the weft inserting means 'may be actuated without Waiting for these parts to pass its path of movement, thus contributing to increased speed of the loom and increased cloth production.

In order'to properly position the tuft yarn and correlate the grippers therewith as they seize the tuft yarn in their upper position, the present invention provides positioning blades which are mounted upon the slide 88,

Figs. 1 and 2, and connects the slide to actuating means for moving the slide towards the tuft yarn presenting position as the grippers rise to take the yarn. One appropriate means for eifectingthe movement of the slide consists of a guide 89 in which the slide is mounted for sliding movement. Connected to the slide is a rod 90, Fig. 1, which extends rearwardly and is connected at 91 with a lever 92 pivotally mounted at 93 and normally held in its frontward position against the cam 94 by means of a spring 95. The cam 94 may be appropriately secured to theshaft 57 to efiect frontward movement of the slide and the blade positioning devices and to again permit the slide to retreat. under the action of the spring 95.

Mounted upon the slide 88 is a transversely hold the blades and rack in operative engagement a cover plate 100 may be appro riately secured to the bar 96 and bear direct y upon the top edge portion of the positioning blades, the loweredge portions of which are preferably bevelled, as indicated at 101, Fig. 12,

the effect being that when the slide 88 is moved rearwardly, the positioning blades 99 enter between the tuft tubes of the presenting mechanism and position the tuft yarn for seizure by the grippers.

Also mounted upon the slide 88 is a plate 102, Fig. 2, which is preferably secured between the bar 96 and the top of the slide, and the front edge portion of the plate 102 is provided with a series of teeth 103, Figsf 11, 12 and 13, the spaces of which correspond to the spaces between the blades 99, the effect being that as the slide is moved rearwardly, the tuft yarn extending from the presenting mechanism is not only positioned for the action of the grippers but is held between the teeth of the plate 102 for the cutting operation. It'is important that the tuft yarn extending from the tuft yarn presenting tubes be held securely in the teeth 103 of the plate which, as it moves backwardly, is liable to displace the yarn, and to this end, thegrippers, which now have seized the yarn, are

given a slight frontward movement to deflect the tuft yarn out of a vertical line frontwardly towards the teeth of the plate 102 and securely position it therein.

Hercto fore it has been common to provide cuttmg mechanism for severing the yarn drawn from the presenting mechanism by the grippers and such cutting mechanism has usually been maintained in its operative cutting position sothat when it is moved transversely of the loom it may cut or sever the tuft yarn between the tubes and the grippers. In accordance with the present invention, the cutting mechanism is given a similar movement transversely of the loom, but the cutter itself is normally held in an inoperative position when it'is idle, in order that the tuft yarn opposite thereto may be properly positioned the present instance of the invention, the cutting blade 105 is carried by an arm 106 pivotally mounted at 107 to the carriage 104, and connected with the arm 106 on which the cutter is mounted is the cutter actuating means which consists of mechanism for imparting to the cutter and cutter carriage the. active This operating mechanism may be variously contrived and as indicated in the present instance of the invention, may be a flexible member, such as a rope or the like 108, secured to the pivoted arm 106at 109, and extending. to the opposite side thereof, as indicated at '110. -VVhen the cutter car-- riage has been moved transversely of the loom to cut the tuft yarn, it is returned to its initial position at the opposite side" of the loom by means of the portion 110 of the cutter actuating mechanism, and sincesuch portion is connected to the swinging arm 106, the cutter itself is swung or moved from its operative to aninoperative position, so that the rear end of the cutter is within the line of teeth 103 formed on the plate 102. When the tuft yarn is to be cut, the portion 108 of the cutter actuating mechanism first effects movement of the cutter to its operative or outer position with respect to the teeth 103 and upon movement of the carriage transversely of the loom, all of .the tuft yarn is cut.

From the above it will be noted that the tuft yarn cutter is normally held-in an inoperative position'relative to theteeth of the toothed plate 102, so that the tuft yarn may be properly positioned in the teeth 103 for the cutting operation without interference by the cutter itself. A spring 111 serves to hold the cutter 105 closely against the bottom of 1 the toothed plate 102- and may be secured to the arm 106 by a screw 112 and adjusted as to its tension by the adjusting hand piece 113.

It has been customary heretofore in -tuft pile fabrielooms to provide abreast comb by cutting a bar to form rearwardly projects ing teeth,-but such formation of the breast comb detracts from accuracy of its formation and is objectionably expensive. One of the features of the present invention, therefore,

is-to providea breast comb which shall be formed of a number of separate andindependent teeth relatlvely positioned on the breast beam and held in assembledrelation In accordance with the present invention, the breast-comb lS'lOIIIlBd. of a plurality of separate teeth .114, Fig. 16, which may be readily fabricated or cut from appropriately sized sheetmaterial. Each comb tooth has a tuft yarn receiving face 115 which extends upwardly and frontwardl of the tooth and is provided on one ofits edge portions, which extend frontwardly, with means for cooperating with the teeth holding device's. Y In the present instance of the invention, each tooth 114 is provided .withan upwardly extending lug 116, Fig. 16, which may beformed by cutting out recesses 117 at each side tl1ere of the precise form of such. detail, however, is not material,'t he essential being that the teeth of the breast comb be made separate and independent of each other and held in spaced relation upon thelbreast beam. In the resent instance of the invention, the breast cam is provided with a recess 118, Fig. 14, and in the bottom of the breast beam recess isthe spacer 119 for properly spacing the separate teeth in theircorrelated position to form the breast comb. In the present instance'the spacer comprises a rack 120 from the bottom portion" of which extend the upward projecting lugs 121 forming spaces therebetween for the reception of the individual and'separate teeth of the comb. The

spacer may be secured in the recess of the breast beam by suitable means, such as the screw 122.

Over-lying the separate comb teeth 11-1, as shown, is a cover plate 123 held to the breast beam by securing means, such as the screw 124, and such cover plate is provided with an interlocking recess 125 into which may teeth is insured to a far greater extent than .is the case when the comb teeth are formed I in a comb bar by kerfscut therein.

As hereinbeforeindlcated, the lay 13 carries a 'series of dents for beating up the successive weft threads as they are laid in the shed, and since the dents sustainrthe full blow f of the beat-up movement they mustbe securely and accurately positioned on and held to the lay. It becomes desirable at. times to remove one or more of the dents from the -la'y,-either for repair or other purposes, or for varying the gageof the reed formed by the dents, and the present invention provides an effective "and simple means for this purpose.

In accordance with the present invention, I the lay 13, Fig. 14-, is provided with a recess 126 for receiving the heel portions 127 of the dents, each of which has the shoulder por tion: 128 which rests upon the top of the rear"- wall of the recess, to thereby sustain the blow.

I of the beat up. 7 The dents 14 are formed separately'an'd are positioned in'the'recess 126 of the lay by means of spacers 129 each of which may be formed as indicated in Fig. 17; that is, the spacers 129 may be formed of sheet material rovided with a series-of teeth 130 extending rom an edge portion thereof, of such gage as desired for the dents. The heel portion 127 of each dent is received in the opening between the teeth 130 of the spacers, thereby properly spacing the dents in their relation to each other. In the lower part of the lay recess'126 is a spacer 131 which may extend into the material of theflay and project upwardly as indicated in 'Fig. '14.

.edge portions of which The upwardly extending edge portion of the s acer 131, a section'of which is indicated in ig. 18, is provided with teeth 132, the up" er are prefera ly bevelled, as indicated, and the heel portion 127 of the dents is provided with a recess 133 which straddles the body portion of the spacer 131 when the heel portion 127 is engaged bctwecn the teeth of the spacer. It may be desirable to form the spacers of sheet mate'- rial in some instances, and in such case the spacers 129 may be provided with downwardly extending flanges134 to overlap the front and rear faces of the lay, and such spacers may be secured to the lay by means such as the screws 135;

The spacers as thus far describedmaintain the dents in their separated and spaced relation, and in order that they may be held seated in the recess of the lay reed removable therefrom, the present invention"contemplates locking means for the dents. In the present instance of the invention, theheel portion 127 of each dent is provided with a recess atone upwardly extending edge thereof, as indicated at 136, and thelocking key 137 has a projection 138 to engage the recess 136. v In order to accommodate the locking key 137 the adjacent wall of the lay recess is cut away as at 139 and the locking key ex: tends upwardly in the recess to a point substantially adjacent to and underlyingone of the spacers"129.

The locking keys 137 are preferably formed in short sections or lengths and may be held in operative engagement with the dents by means such as the screwor screws 140, the construction being such that upon backlng off the key holding means or screws 140, any sec tion of the locking keys may be released from the recesses 136 of the dent heels, so that by meansfor causing the dents and grippers to be moved in a path non-intersecting with the path of movement of the weft inserting means during the idle movement ofthe grippers and lay to permit insertion of the weft during such idle movements whereby increased speed of production ofa tuft pile fabric is secured.
